According to Oregon State Police, the relationship between 35-year-old Lost River High School teacher Jeffrey Vincent allegedly started when the student was still attending high school at the age of 18.
The now-former student is currently 19-years-old.
Police said the relationship had gone on for “a significant period.”
On July 6, 2017, police arrested Vincent on charges of official misconduct, coercion and tampering with a witness.
Vincent was placed on administrative leave by the Klamath County School district pending results of the investigation.
